1. CSS stands for Cascading Style
Sheets and is a simple styling language which allows attaching style to HTML
elements. Every element type as well as every occurrence of a specific element
within that type can be declared a unique style, e.g. margins, positioning,
color or size.

3. CSS is a language that adds style (colors, images, borders, margins…) to
your site. It’s really that simple. CSS is not used to put any content on your
site, it’s just there to take the content you have and make it pretty. First
thing you do is link a CSS-file to your HTML document. Do this by adding this
line: <link rel="stylesheet" href="style.css"
type="text/css"> The line should be placed in between your
<head> and </head> tags. If you have several pages you could add the
exact same line to all of them and they will all use the same stylesheet, but
more about that later. Let’s look inside the file "style.css" we just
linked to. h1 { font-size: 40px; height: 200px; } .warning { color: Red;
font-weight: bold; } #footer { background-color: Gray; }

4. Cascading Style Sheets (CSS) is a simple mechanism for adding style (e.g.
fonts, colors, and spacing) to Web documents. This is also where information
meets the artistic abilities of a web-designer. CSS helps you spice up your web-page
and make it look neat in wide variety of aspects.
